COT-BED.

Specification of Letters Patent.

Patented Apr. 26, 1910.

Application filed January 4, 1909. Serial No. 470,612;

To all whom it may concern:

Be it known that I, CLARENCE H. YOUNG, a citizen of the United States, and a resident of Rockland, in the county of Plymouth and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Cot-Beds, of which the following is a specification.

This invention relates to what are usually termed cot beds, although it is equall well adapted to swing beds, and it'has or its object the effecting of certain improvements in the mattress-supporting means, as hereinafter set forth.

Referring to the drawings forming part of this specification, Figure l is a pers ective A view of a cot bed or swinging ed made in accordance with my invention. Fig. 2.is a plan view, with parts broken away and in section, of a portion of the mattress support. Fi 3 is a detail vertical section illustrating t e spring-engaging member of the invention. 7 Fig. 4 is a plan view, with parts broken away and in section, of a portion of the mattress support constructed in a slightly different manner; Fig. 5 is a de tail vertical section of the latter construction.

. The frame of this bed is preferably composed of the two end-members consisting each 'of a length of iping bent into an inverted U designated ythe reference numeral 1," and ri idly connected by "the longitudinal braceare 2, as shown in, Fig. 1. To each end-member is attached a horizontal angle-iron 3, and between these angle irons is stretched a sheet of duck, canvas orrother strong woven fabric by means of the helical springs 5 engaging both the ends of' such fabrie and the horizontal webs of the angle ironsu Theenga ement of said helical-springs with the fa ric may be in any convenient and durable manner, al-

,;fthou'gh I prefer to arrange the same as here- TtO'jfhe canvas or other fabric 4, the advaninQa-fter set forth. In whatever way, however, the suspension springs- 5 are attached tages of theconstruction are numerous. In the first place, the helical springs keep the fabric in a resiliently taut condit on, and

renderthe bed a ve comfortable one upon which: to lie, even without a'mattress superposedthereon. Second, any woven fabric, even the best of duck,.is sure to stretch more or less unevenly, depending upon what section thereof is mostheavlly used, but byup' by the consequent shortening of the particular sprin s tensionin such sections, and there will e no sag a ong any parts of the fabric, but every part will be kept equally taut.

To still further improve this bed, I provide the ends of the canvas with resiliently flexible strengthening members to which to attach the helical springs, for the pur pose, mainly, of insuring against the possibility of the s rings tearing loose from the canvas. One orm of such members is the slender metal rod 6 held in a hem 7 at each endof the fabric 4; the hooked ends 8. of the springs 5 being inserted through the cloth into en agement with said rods. This is illustrate in Figs. 2 and 3. Another form of said members is shown in Fi s. 4 and 5 and consists of strap metal 9prov1ded with holes 10 therein for the penetration of said hooks. One advantage of this strap metal is that the fabric can be wrappe about it sufficiently to hold its place thereon without stitching any hem for the purpose.

Another advantage consists in more securely holding the hooks against lateral displacement, and wear and tear of the fabric. To insure the lateraledges of the fabric against undue stretching, I prefer to form a hem 11 at each side, and locate in each hem a strong cord or-rope 12 the ends of which are made fast to the ends of the members 6 or 9, in suitable eyes 13 13 thereat, as shown in Figs. 2, and 4. In-employin the strengthening members 6 or 9, it is wel to have them sufficiently flexible to permit the springs 5 to take up any slack which may be caused along any section of the 'canvas by stretching due to use.

To enable this cot bed to be em loyed as a swing bed, a small hole 14 is ormed at each end of each angle iron 3 for the reception of a ring or hook 15 to which thesuspension ropes 16 can be secured, as shown 1n Fig. 1.

What I cla1m as my inventlon and for which I desire Letters Patent is as follows,
